For the last few days I have been looking at the lambs with the sense that something is not right with them, but haven’t been able to put my finger on it. The top 80%-90% are still doing great, but a few of them actually seem to be going backwards. I had a little trouble with meningeal worm a few weeks ago, but I was able to save the five that came down with it and keep the rest from getting it, but I haven’t felt like it was related to that. I haven’t changed their feed or anything like that. So, what is it? What’s the problem? Disease? It doesn’t seem like it. If if it’s not the feed, not parasites and not disease, then what?
Yesterday I had to grab a lamb out of the finishing pen and put him in the sick pen because all of a sudden he was totally sunken, caved in around the middle. When I grabbed him, I couldn’t help but say “Whoa” out loud because he had substantially less fat cover than he should have. He has been on my radar for about five days or so, but only because I felt like he was lagging, not because I thought there was something really wrong with him. I had been thinking that I would swap him out of the finishing pen for one of the beefier lambs that are still out on grass, but when I saw him yesterday, and then especially when I felt him, I realized he had to go into the sick pen. But, why?
Putting a sheep into the sick pen by itself stresses it out, which defeats the whole purpose of the sick pen, so after putting the sunken sheep into the sick pen, I went out and grabbed #85 who I have been watching for weeks. Number 85 has a healthy appetite, drinks plenty of water, has lots of energy, and is always bright and alert, and though he is definitely in the bottom 5%, his frame continues to grow, but he is a skinny minny. He is just not putting much meat on those bones. Since the sunken sheep needed a pen mate, I thought it was an opportune time to bring #85 in to give him some individual attention to see if I can’t get him to start filling out his frame (my feeling is that he has something wrong with him, something genetic or congenital, or something chronic and unresolvable [economically-speaking], but it is still worth a try).
While I was looking over the group trying to pick out #85, my eyes landed on the few that I feel like are going backwards, and I asked myself a little exasperatedly, “Why are these sheep tanking?!” and then it hit me – minerals. It was probably the minerals! All along I have been feeding the lambs minerals (Fertrell Graziers Choice) out of three six foot long feed troughs because that is what I had handy. However, I am raising these lambs on a contract that includes a weekly slaughter schedule of eight to ten lambs, and about three weeks ago, I decided that the bottom half of the pasture lambs were not growing fast enough for me to be able to meet that schedule. At the rate they were growing it seemed there would be a week or two gap in getting the lambs to slaughter weight. So, wanting to stay on schedule, I put all of the pasture lambs on grain (per the contract, these lambs are grain finished) to get them growing faster in an effort to close the gap, which is working (Ordinarily, I pull eight to ten of the pasture lambs into the finishing pen every week after I take a group to slaughter, in order to keep a month’s worth of lambs in the finishing pen. That way all of the lambs will have received one to two pounds of grain per day for a month before being taken to slaughter.). However, in order to put them on grain, I needed to use the six foot troughs as grain feeders. Because of time constraints I stopped feeding the minerals (if I had more time I could hang around and give the lambs minerals after they finished their grain). Now, three weeks later, some of the lambs are starting to tank, which, knowing absolutely nothing about the metabolism of minerals, I guess is about the right amount of time for the body to use up the minerals and micronutrients contained in the mineral mix and start suffering from a deficiency of one or more of them.
So, yesterday I started making more time. I am now feeding the lambs their grain and then when they are finished, I give them minerals.
If it is the minerals, I think I will know pretty quickly.
In the meantime, the sunken lamb and #85 will get a little extra attention in the sick pen.
(The answer to the question, why don’t you just get mineral feeders? is money. Moneywise the farm has not done well this year and I do not have the cash to invest in any new equipment, no matter how small the expense. I still have hay to pay for, and a substantial percentage of the cash to pay for that hay, which will get the breeding flock through the winter is supposed to be coming from these feeder lambs. Time, while short, is currently not as short as cash.)
